Ngadha (also known as Ngada or Ngad'a) is an Austronesian language, one of six languages spoken in the central stretch of the Indonesian island of Flores.[2] From west to east these languages are: Ngadha, Nage, Keo, Ende, Lio, and Palu'e. These languages form the proposed Central Flores group of the Sumba–Flores languages, according to Blust (2009).[3]

Ngadha is "bizarre" because it has no prefixes nor suffixes at all.[5] This "strangely streamlined language" is thought by linguist John McWhorter to have originated when "little people" were "subjugated" into the Austronesian population.[5] McWhorter (2006) speculates this rare linguistic transformation would have occurred to the ancestor of Ngadha and the related Keo and Rongga languages.[5] Nonetheless, in basic vocabulary, such as body parts, numbers, and action verbs, Ngadha has kept 94 out of a list of 247 lexical items of the Proto-Malayo-Polynesian language.[6]
